Application filed October 1, 192 5, s ei 59,9 7, ei1d-in Great Bri tai hoctbber 30,1924] I This invention has reference to ballsof the kind used or for playing the game ofcricket, hockey and similar games, which are used on wet ground, or under similar conditions; and it l-has primarily for its object and effect to provide balls of this kind which arenot so liable to be damaged by wet, or lose their normal quality under the conditions of play, or use.

In this ball, the core'is'enclosed within an outer cover of material such as guttapercha, balata, rubber or rubber compound "or like material, or a mixture of such materials--instead of leather Whichis usuallyv employed as the covering -which is applied by moulding it on to worsted or like soft material which forms the core, or outer layer of the core of the ball; that is the gutta-percha, balata or like outer cover is pressed on to the soft core material, by which, and the application also of heat, a firm adhesion or amalgamation of the core and the covering of gutta-percha, balata,

rubber, or rubber compound or the like, is

' obtained.

This outer covering is according tov one method of application applied inthe form of two semi-spherical cups, and they are placed over the core or body of the ball and subjected to pressure and heat in suitable moulds. i a

A hard ball so constructed will be impervious to wet, and will keep its shape and playing qualities under the circumstances as stated; and these qualities will be preserved for a relatively great length of time; and

I with regard to its re-action on the hockey stick, clubor'bat, the efi'ect on the hands of the player is generally more pleasing than with balls of ordinary constructions The ball is very serviceable where it is subjected to'hard wear, such as is required in a ball used for cricket and base ball practice, and under similar circumstances.

A ball made according to this invention,

is illustrated in cross section in the drawing.

In this drawing, 1 is the outer covering of gutta-percha, balata, rubber,-or rubber compound or like material, or a mixture of such materials; 2 is the covering of worsted or like materialdirectly within it, which forms the outer part of the core, and within which are other core laminae ,3 consisting of worsted or like quilts, and 4 consisting of cork and rubber, or similar compound or material; the latter being similarly applied jecting them to e, by ass each layer or cover spherical cups of the size and diameter re 7 quired, and applying them, by pressure, or pressure and heat, in the manner herein described.

l/Vithin the core parts 3, 4, is the centre or matrix spherical core 5, which may be cork and rubber or like material, or of any suitable substance. I

'In manufacture, the cork and'rubber, or like compound or material laminae 4, are, spherical cups, and they are applied by plac mg them in semi-spherical moulds, with the central ball partwithin them, and then subpressure of the required intensity, such as is used inmanufacturing golf balls, and also subjecting them to heat by heating the moulds. 'After each pair of hollow cups is applied a layer or covering3 of worsted or the like, forming a quilt or blanket, is applied over them in any suitable known way; and then the subsequent covering of the cork and rubberor like material 4 is similarly applied. Finally over the last covering '3, the outer cover of gutta-percha or the like rubber, or rubber compound or a mixture of same is applied compressed under heat, "as above described.

or-parts as's tated, made oftwo hollow semia and compressed,

By the outer covering, or the outer and i and core cups are joined or Welded, and a firm adhesion or amalgamation of the outer cover 1, with the worsted orlike core parts or quilts is obtained. After the ball is so made it is vulcanized in the usual way of vulcanizing golf and similar balls.

In some cases the of all the hemispherical cups may be effected at once, by one act of compression in the moulds. I y x The proportion of thickness of the different coverings or lamlnae shown in the drawings, is a suit-able one. The surface ofthe outer covering 1 may be smooth, or slightly with a suitable pattern.

What is claimed is i 1. A ball comprising an inner spherical mass of cork and rubber and concentric enveloping layers alternately of cork and rubber and worsted, the cork and rubber rough, or furnished joining and compression layers being in se1ni-spl1erioal hollow form and united at their edges subsequent totheir; application, the final layer being of a comparatively thin resilient character compressed under heat.

2. A ball comprising an innerspherical mass of cork and rubber and concentric enveloping; layers alternately of? cork and rubber and worsted, the cork and rubber layers being in semi-spherical hollow form and united at their edges subsequent to their In testimony whereof I have signed my name to this specification, 7
